fred_gnp which has suddenly stopped working usingPipeline. To avoid attaching the entire notebook, the following code raises the error locally.
from quantopian.pipeline.filters import StaticAssets
from quantopian.pipeline import Pipeline, CustomFactor
from quantopian.research import run_pipeline
from quantopian.pipeline.data.quandl import fred_gnp
class LatestMacroEconomic(CustomFactor):
window_length = 1
def compute(self, today, asset_ids, out, values):
out[:] = values[-1]
pipe = Pipeline(
columns={
'fred_gnp': LatestMacroEconomic(inputs=[fred_gnp.value])},
screen=StaticAssets([symbols('AAPL')])
)
df = run_pipeline(pipe, '2017-01-01', '2017-12-01')
